Eh… debatable. I’ve seen people grab a fistful of it with no ill effects.
The main thing is that you can’t touch it.. for very long. Unlike water
ice, which melts into really cold water. CO2 ice melts into really cold
gas, which doesn’t really do anything to you.﻿

Oh, other potential danger…. keep in well-ventilated area. CO2 causes
drowsyness above 1% concentration in the air, and potentially deadly above
5%, even in sufficient oxygen. 1 kg of dry ice can lethally poison a 2.5
meter-high sealed room of 6.7 m^2 floorspace. 10 kg of dry ice could do the
same to a 66.7 m^2 room. That’s about 720 square feet. It gets worse at
altitude, where the air is less dense. In Denver, it could probably poison
900 square feet or so to the same extent.﻿
